I choose my car expecting it to give me all 300HP that Bmw said it has. I'm not going save a few bucks by putting in cheap gas so i could have less.

Its like someone buying a top of the line Macbook Pro and then go cheap by hooking it up with dial up connection because you saved a few bucks by not getting cable/Fios. Lease or finance I treat my cars as if its nearly a member of the family (my wife hates me for it lol)
